HAROLD A. NOUBSE, OF ST. PAUL, MINNESOTA.

BEOODER.

To all whom it may concern:

Be it known that I, HAROLD A. NoURsE, a citizen of the United States, residing in St. Paul, in the county of Ramsey and State of .Minnesota, have invented a new and useful Improvement in Brooders, of which the following is a specification.

My invention relates to improvements in brooders, and more particularly to that class of brooders heated by hot air.

It has for its object the production of an eflicient brooder adequately heated and ventilated.

In the accompanying drawings forming part of this specification, Figure 1 is a plan of the hover end of my improved brooder. Fig. 2 is an elevation partly in section. Fig. 3 is a longitudinal section taken on the line X X of Fig. 2.

In the drawings A is the brooder house, B the hover, C the lamp, and D the heating drum. The bottom of the brooder is double, consisting of an upper floor 1 and a lower floor 2. The rear wall 3 is constructed with a slot 4 opening into a space between the floors. This slot is provided with a hood 5 to prevent unnecessary draft. Through this slot the air for the hereinafter described ventilating system is admitted.

The heating drum D comprises the vertical flues (5 and 7, the transverse flue 8 and the longitudinal flue 9. An inner tube 10 opens into the vertical flue 7 near the floor of the brooder and at its upper end into the flue 9. This flue 9 has a horizontal extension 11 which connects with the chimney 12 and thus opens into the outer air. The flues 6, 7, 8 and 9, with the tube 10 form a continuous passageway, the only openings into them being that at the base of the flue 6 for a suitable heater, that at the base of the flue 7 below the floor 2, and at 18 with the inner tube 10 which through the flue 9, its extension 11 and the chimney 12 carries away the products of combustion, none of which are permitted to enter the brooder.

The hover B runs across the brooder, being inclosed by the ceiling l l, flue box 14, the angular end walls 15 and side curtain 16. The parts let and 14 are permanently attached to each other and form a removable lid to the hover chamber. The walls 15 are rigidly connected with the brooder house. I have found these angular end walls partic- Speeification of Letters Patent.

ularly efficient, both because they conveniently insulate the flues 6 and 7 from the brood chamber, and because they make it impossible for chicks to crowd and smother each other at the point of greatest heat. It will be apparent to those skilled in the art that there is no place within my hover chamber at which an undue crowding of the chicks is possible. By the use of the system of fines above described the heating of the hover is as nearly uniform as it is possible to make it, but of course the temperature upon the floor will be slightly greater at the angles 17 of the walls 15. The natural tendency of the chicks, if cold, is to crowd to this point, but in the event of this occurring in my brooder, the chicks first approaching the points 17 cannot be overheated or crushed, because if any crowding occurs they will be pushed outward along the angular wall 15. Below the flue 8 a screen 18 is provided carried by the frame 19, and the flue box 14: is protected by a metal or asbestos lining 20. The openings 21 through the floor 1 are considerably larger than the diameter of the lines 6 and 7 which pass through them, for the double purpose of insulating the floors from the heat of the fines and to furnish a passage the brooder, thence following the flues into the flue box 14, whence it is free to circulate, through the screen 18, in the hover chamber.

A source of heat, such as the lamp C, is placed under the flue 6 and connected therewith by suitable means, such as the chimney 82.

The heating drum, as well as the hover, may be easily taken apart for purposes of inspection and cleaning. The flues 6 and 7 (with the flue 8 attached) may be lifted ofl from the collars 39 at their bases; the tube 10 is formed with telescopic joints where it passes through the top of the flue box 14: and the flue 9 and chimney 12 are also separable. In other words, the longitudinal flue 9 is slidably connected with both the tube 10 and chimney 12, while the fines 6 and 7 are supported by, but not attached to,

the collars 39. Thus to separate the parts the section of the drum D above the hover is first removed; then the ceiling 1a with the attached flue box 14: is lifted off, after which the attached fiues 6, 7, and 8 may be taken out of the brooder.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

1. In a brooder, the combination of a sec tional and removable heating drum, and a hover chamber provided with stationary end walls projecting into said chamber and forming an air conduit between the drum and said chamber and a removable lid carrying a line box for the drum.

2. In a brooder, a hover extending transversely across it and having triangular chambers at its ends, in combination with a sectional separable heating drum, said drum including vertical flues passing through said triangular chambers and a removable lid for the hover chamber, said lid consisting of a fine box and drop ceiling.

3. In a brooder, the combination of a heating drum composed of vertical and horizontal flues, a hover chamber having angular end walls inclosing the vertical lines and extending into said chamber and an overhead horizontal flue box, open beneath, with a screen between it and the hover chamber.

In a breeder, a hover having chambers at its ends, a heating drum comprising ver- -tical flues extending through said chambers,

overhead horizontal tlues, one above and atright angles to the other, an inner tube open at both ends and forming a conduit for the products of combustion between one of the vertical tlues and the upper horizontal flue and a chimney connected with said last mentioned flue.

In a brooder, a removable hover extending transversely across it and having fixed chambers projecting into its ends, in combination with a sectional heating drum including vertical flues extending through said chambers, a horizontal flue uniting said vertical flues, a second horizontal flue and an inner tube open at both ends, connecting one of the vertical flues with the last mentioned horizontal flue.

6. In a brooder, the combination of an adjustable heating drum comprising vertical and horizontal flues and an inner tube, a lamp provided with a chimney connecting with one of said vertical fines and a hover chamber, provided with a screened overhead flue box for one of said horizontal dues and triangular boxes inclosing the vertical flues, each of said last mentioned boxes having an apex projecting centrally into said hover chamber.
